I meant the capability split - let's say you support 4-way-HS only for
client, but not for AP. Then you have to support the NEW_KEY command
for the AP case, even if you might not support non-offloaded 4-way-HS
for the client case.
So if something supports the following:
* client: offloaded 4-way-HS only
* AP: not offloaded 4-way-HS only
Then you have to support NEW_KEY (AP case) and then using NEW_KEY to
detect whether or not a wpa_s configuration option to not use offloaded
4-way-HS can be used will not work correctly.
I don't really see that this is a sensible configuration, but I could
imagine it existing if somebody "bolted on" AP functionality for a
client-side chipset or something like that.
Again, I think I'm happy to leave this up to you - this kind of
configuration option should really only be used for debugging anyway,
so just getting errors later is probably fine.
